However, the Saints were lucky to pick up all three points with goalkeeper Brendan Clarke the main reason the visitors clinched a narrow win.His display between the posts denied Derry from continuing their mini revival with a string of superb saves in the latter stages.Earlier St Pat's made the better start and almost took the lead within 60 seconds with Keith Fahey's shot well saved by Gerard Doherty.Few chances followed until five minutes from the break with City's Shaun Kelly failing to test the keeper as he fired over the bar when well position in the box.In first half stoppage time Killian Brennan tried his luck with a free kick from 25 yards out and Dohety was relieved to see his effort skim the post.The second half was only two minutes old when St Pat's scoring what proved to be the decisive blow. A neat build-up ended with Aaron Greene drilling an unstoppable shot past Doherty.Derry responded with Philip Lowry having a goal-bound shot blocked on the line by Sean Hoare. Then Stephen Dooley smashed a shot off the post as the home side pushed for an equaliser.City missed another golden chance on 74 minutes when Houston burst into the box, but Clarke came to the rescue for the Saints.Keeper Clarke was again to foil Derry's best attempts to hit the net as he kept out Patrick McEleney's 20 yard drive before tipping over Barry McNamee's well struck free-kick.City battled to the end but to no avail although they can feel disappointed they failed to take anything from this league clash.Full time.
